Abstract
At least two or more plastic films are adhered via an adhesive layer or layers to produce a laminate plate having a total thickness of the plastic films of 250 to 700 μm, and then the laminate plate is subjected to die cutting to obtain a surface protection plate 5. The thickness of each plastic film is preferably chosen to be 50 to 400 μm. A surface protection plate having superior rigidity can be thereby easily produced with a smaller thickness. The thus obtained surface protection plate 5 can be suitably used as the surface protection plate 5 of the liquid crystal display 6.
